WRV200 VPN problem with Dynamic IP

I have a WRV200 router on a dynamic IP address that I want to create an IPSEC tunnel to from a RV-082 on a static IP address. In the setup of the RV-082 IPSEC tunnel I need to set up a "Remote Security Gateway Type". My choices are IP, dynamic IP + email address, or dynamic IP + FQDN. Since my WRV200 is on a dynamic IP I have to choose one of the later two choices. The WRV200 does not have an entry to set this. Can someone shed some light on how I do this. Thanks in advance.
